BOX NAILING AND PRINTING MACH|NE.

SPECIFICATION forming par@ of Letters Patent No.' 608,917, dated August e, 189s. Application filed December 7,1897. Serial No. 661,031. (No model.)

To all whom t may concern:

Be it known that I, FREDERICK P. RosBAcK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Box Nailingand PrintingMachines, of which the following is a specication.

This invention relates to box-nailing ma- 1o chines generally, and more especially to an improved machine for use in the'construction of wire-bound packing-boxes to fasten the ends of the boxes in place by nailing them to the end reinforcingcleats. The machine i 5 is also provided with printing mechanism,

whereby advertisements may be printed upon` the ends of the boxes.

My object is to provide a machine of generally-improved construction, adapting it more 2o especially for fastening the sides and bottom to the ends in the construction of wire-bound boxes, whereby` the operation may be performed with economy in time and labor. They wire-bound box referred to consists of a sheet 25 in one or more sections, reinforced on one side with cleats and at its opposite side with strengthening-wires, the sheet and wires be ing fastened with staples to the cleats, and l the blank thus formed being step-mitered 3o and bent at the step-ruiter cuts to form the top, bottom, and sides of the box. A wire-V bound box is shown in perspective in Figure 37. These boxes may be of any size and shape and are particularly desirable on ac- 3 5 count of their strength and lightness.

My invention is not to be limited to the use of printing mechanism in combination with the box-nailing mechanism, because my primary object is to provide a machine which 4o will drive nails at three edges of the box end in one operation, and the printing of the box ends, though very desirable in many instances, is a secondary object.

In the drawings, Fig. 1 is a side elevation 4 5 of myimproved box nailing and printing ma chine; Fig. 2, an elevation of the opposite side of the machine; Fig. 3, a rear end elevation thereof; Fig. `4, a vertical section taken on line 4 of Fig. 1; Figs. 5, (i, and 7, enlarged 5o broken sections taken on lines 5, 6, and 7 of Fig. 2; Fig. 3, an enlarged broken section taken on line 3 of Fig. 5; Fig. 9, a broken plan section taken on` line 9 of Fig. 8; Fig. 10, a broken section taken on line 10 of Fig. 9 and showing details ofl clutch mechanism; 55 Figs. 1l and l2, sections taken, respectively, on lines 11 and 12of Fig.`10; Fig. 13, an enlarged sectional detail View of another clutch mechanism, the sectionbeing taken on line 13 of Fig. 9; Fig. 14, an enlarged and broken 6o section taken on line 14 of Fig. 5 and illustrating the constructionof one of the naildrivers; Fig. 15, a section taken on line 15 ofFig." 14; Fig. 16,`a section taken on line 1G of Fig. 5; Fig. 17, an enlarged broken view, 65 partly in section and partly in side elevation, illustrating nail-feeding mechanism; Fig. 18, a broken sectional view taken on line 18 of Fig. 17 Fig. 19, a broken section taken on line 19 of Fig. 1S; Fig`.` 20, a broken view showing sections taken on the lines 20 2f() of Fig. 19; Fig. 2l, a broken view, partly plan and partly sectional, the section being taken on line 21 of Fig. 19; Fig. 22, a broken section p illustrating details of construction of the parts 7 5 Villustrated in Figs. 17 to 21, inclusive; Figs.

IOO

In each instance sectional figures are to be viewed in the direction of the arrows at the lines on which the sections are taken.

A is the frame of the machine, formed with side frames or cheeks A A2, mounted upon4 feet A3, rear end A1, cross-braces A5, and forward cheek extensions A6 A7, having legs A S.

B is the drive-shaft, provided with a pulley B, which is belted to a pulley on a line-shaft or the like to rotate and tu rn the shaft B constantly. Fixed to the shaft B is a pinion B2. Jonrnaled in the cheeks above the shaft B is a counter-shaft C. On the shaft C are two fixed collars C C2, and between the collars is a gear-wheel C2, having a hub C1, which is normally loose upon the shaft C. The gearwheel C3 meshes with the pinion B2 and rotates constantly, but being normally loose upon the shaft C the latter is normally at rest.

In the shaft C (see Figs. l0, ll, and l2) is a longitudinally-extending concave recess of a length which causes it to extend beneath the collars C C2 and hub C1. Resting in the recess is a rocking clutch-pin provided at one end with a laterally-extending arm 2, having a cam edge 3 and stop projection 4. In the collar C is a radial recess 5, through which the arm 2 extends, and in the said'recess and connected at one end with the arm 2 and at its opposite end to the collar is a spring 15. The pin is cylindrical at the ends; but between the ends, where it passes through the hub C4, it is half-round, being formed so by a recess 7 in the pin. The spring 6 tends to draw the arm 2 and rock the pin to the position indicated in Fig. l2, whereby it will engage one of two recesses or notches 8 in the inner circumference of the hub C1. Vhen the arm 2 is in the position indicated in Fig. ll, the pin 7 is rocked to the left from the position shown in Fig. 12, whereby the halfround portion of the pin is altogether in the recess t of the shaft, and the hub will move over it without being engaged by the pin. In other words, when the parts are in the position shown in Fig. 1l the gear-wheel C2 rotates loosely upon the shaft C, and when the parts are in the position shown in Fig. 12 the shaft C is locked to the gear-wheel C3 and rotates therewith. Fulcrumed at 9 on the cheelcA is a lever 10, connected by a rod 11 with a bell-crank lever 12, held normally in the position shown in Fig. l by a spring 13. Connected at its lower end with an arm of the bell-crank lever is an upward-extending rod 11. (See Fig. Il.) A lever 15, fulcrumed between its ends on a bracket wat the cheek AQ is pivotally connected at one end to the rod 111 and at its opposite end carries a downl ward-projecting lip 17, which in the rotation when it is desired that the shaft C and attendant parts shall rotate the handle 10 is moved by the operator to the left in Fig. l to swing the bell-crank lever 12 against theresistance of the spring 13 and draw down the rod 11, whereby the lever 15 is turned to lift the lip 17out of engagement with the arm 2. This permits the spring 6 to rock the pin 1 on its axis as soon as a recess 8 registers therewith, whereby it will project into the recess 8 and lock the shaft C to the rotating gearwheel C3. The handle 10 is then immediately released by the operator, whereby the spring 13 exerts itself to press the stop 17 upon the circumference of the collar C. Thus'when the shaft C and collar C' have nearly completed a revolution the lip 1T engages the arm 2 and swings it to the position shown in Fig. 11 just as the shaft has completed a revolution, thereby releasing the shaft from the rotating gear C2.

In the cheeks A A2 are coincident horizontal cross-head guide-openings s for a crosshead or ram D, having a vertical face-plate D. Extending through the ram D and beyond the guides s is a shaft D2. On the shaft C and keyed to opposite ends thereof are disks C5 C5, with which pitmen C11 are eccentrically connected. At their opposite ends the pitmen are pivotally connected to the end of the shaft D2, whereby in each revolution of the shaft C the ram is plunged forward and back in the guides 3.

E is an intermediate gear-wheel mounted upon a counter-shaft E, journalcd in a bearing-sleeve A9, Fig. 9, secured upon or east integral with the cheek AC The gear-wheel E meshes with the gear-wheel C3, whereby it rotates constantly.

F is a counter-shaft journaled at opposite ends in the cheeks A A2. Rigid upon the shaft F are collars F F2, and confined between the collars and normally loose upon the shaft is a gear-wheel F3, meshing with the gear-wheel E and rotated constantly thereby. Extending beneath the collars F' F2 and gearwheel F3 is a groove or recess r in the shaft F, (see, for example, Fig. 13,) and resting in the said groove is a clutch-pin r', in all respects like the clutch-pin t', before described, and provided with a projecting arm r2, extending through a radial recess r3 in the collar F and projecting beyond the circumference of said collar. When the parts are in the position shown in Fig. 13, the gear-wheel F8 turns loosely on the shaft F, and when the pin r' is rocked to the right by the spring r1 the clutch-pin locks the gear-wheel and shaft together, whereby the shaft is rotated by the gear-wheel. A lever T5 is pivoted upon a pin r6, which projects inward from theV cheek A. On one end of the lever T5 is a downward-projecting lip r?, and the lever is held down by a spring rs (see Fig. 5) to press at its lip normally upon the circumference of the collar F to engage the projecting arm r2. On the opposite end portion of the lever of is an up- IOO IIO

ward-projecting arm T2, held normally in an upright position against the stop T10 by a spring T11. The arm T9 extends normally upward into the path of a trip or cam T12, carried by the cross-head or ram D, as shown in Fig. S. The springT11 is weak as compared with the spring T8. In the initial or forward movement of the ram D the cam T12 at its under surface engages the arm T9 and swings it backward against the resistance of the spring T11 until it is passed by the cam. `It then assumes its normal position against the stop T10. In the return or backward movement of the ram the cam T12 at its under surface engages the arm T11, and as the latter is pressed against the stop T10 it yields in the downward direction under the cam, swinging the lever T5 to disengage the lip T7 from the j arm T2 of the clutch-pin. The hub of the gear-wheel F2 is provided on its inner circumference with recesses like the recesses t2, (shown in Fig. 12,) whereby when the arm T2 is released by the lip T7 the pin is turned by the spring T4 into one of saida'ecesses to clutch the shaft F to the gear-wheel F3 and cause the former to rotate. Before the shaft has completed a revolution the arm T9 is released by the cam T12 and the lever T2 is pressed down by the spring T2, whereby the lip T7 will catch the projecting arm T2 and rock the pin to the position of disengaging the shaftuF from the gearwheel F2. rlhus in each operation the shaft F is given one complete revolution.

It will be understood from the above description that when the operator turns the handle t1 the drive-shaft B is given one complete revolution and then stopped. ln this revolution the ram D is moved first in the forward direction and then back to its initial position. As the shaft B nears the completion of its revolution the cam T12 on the ram D turns the clutch mechanism on the shaft F, whereby thc said shaft and attendant parts are given a complete revolution and then stopped. The movement of the shafts B F aro thus intermittent, and the movement of the shaft F follows that of the shaft B, starting just before the stoppage of the latter.

Journaled in the cheek extensions A6 A7 are parallel horizontal shafts q q, (see Figs. 28 and 29,) each carrying apair of laterallyadjustable sprocket-wheels q', overwhich run feed-chains q2, carrying stops or feed projections qs q2. On the cheek extensions is a receptacle for box ends X, comprising a floor or base-plate p, a stationary side plate p', and a vertical back plate p2. Adjustable laterally upon the base-plate p is a vertical guideplate p2. (See Fig. 26.) The feed-chains q2 slide upon the base-plate p, and on the said base plate are longitudinally extending cleats p4, on which the box ends X rest out of contact with the chain and inposition, whereby the lower box end will be engaged by a stop Q3 and moved from beneath the rest of the pile. Beneath the plate 1121s an opening partly closed by an adjustable plate p5,

which maybe adjusted. in accordance with the thickness of the box endand fastened in place by thumb-screws p6. The opening between the plate p5 and base p is thus rendered just large enough to permit one box end and no more to pass through at a time.

G is a printing device which, asshown in the drawings, is capable of printing in two colors. lt comprises two rollers n, mounted at opposite ends in the cheek extensions, with the highest points of their circumferences in the plane of the cleats or guides p4. Above the rollers n are printin g-cylinders Tt. Above the printing-cylinders TZ are ink-troughs n2 and inking-rollers n3. The rollers n are journaled in boxes which rest upon adjustingscrews n4, whereby the distance between them and the cylinders may be regulated in accordance with the thickness of the box ends. On

, the left-hand side of the machine, beyond the cheek extension A7, theshafts of the rollers n Tt 'n3 carry gear wheels and pinions TLS, (see Fig. 2,) which mesh with each other, the lower two gears meshing with a gear-wheel on a shaft m, journaled on the cheek A7. The shaft m also carries sprocket -wheels Tn m2. The

sprocket-wheel m1 is geared to a sprocketi wheel F1 on the shaft F by means of a drivechain m3. The sprocket-wheel m2 is geared to a sprocket-wheel g4 on the rear shaft q by means of a drive-chain m4. Thus each time the shaft F is rotated the feed-chains q2 move to advance a" box end into the printing-machine, and the rollers and cylinders of the printing-machine are rotated to print upon the box end. By providing the two printing mechanisms the box ends may be printed in two colors with suitable advertisements, the feed-chains and printing-cylinders being so geared with relation to each other that the impressions will be suitably placed upon the box ends.

In the face-plate D' of the ram D, toward the upper and lower ends thereof, are hori- Zontal T-grooves Z. Fitting against the faceplate` are vertical nail-drive-attaching bars D2 D4, provided at the slots Z with laterallyextending ends Z', through which extend nutbolts Z2. (See, for example, Fig. 16.) The bars D3 D4 may be adjusted laterally and tightened in adjusted position by means of the nut-bolts Z2, the heads of which engage the T-slots Z, as indicated. In the bars D3 D4 are lon gitudinal T-grooves Z2.

H Il' are nail-drivers, which at their ends are held in socket-pieces H2. The socketpieces H2 are split and tapering, as shown in Fig. 16, and provided on their outer sides with threads to receive nuts H2, which when screwed in one direction clamp the drivers iirmlyin the sockets and when unscrewed loosen the hold of the socket-pieces `upon the drivers, whereby the latter may be removed. The socket-pieces H2 of the drivers H have threaded shanks Z2, terminating in bolt-heads IOO IIO

Z5, and on` the shanks are jam-,nutsl The the bars D3 D'1 and may be slid therein to any desired position and tightened in place by means of the jam-nuts Z0. The socket-pieces which hold the drivers H are provided with shanks Z7, which screw into blocks H1, having ears Z8, through which pass nut-bolts Z0, the heads of which slide in the T-grooves Z.

As hereinafter described, the nailing operation is performed along three edges only of a wire-bound box, being at the sides and base thereof only. The drivers H are upon the bars D3 D4, and the drivers II are at the upper T-groove Z, between the bars D3 D4. In Fig. 5 three drivers I-I are shown at each side and three drivers II' at the top.

It will be understood that the number of drivers may be increased as desired.

I is a pan or reservoir for nails, hinged at its lower forward corner to the tops of the cheeks A A2. On the under side of the reservoir I, at opposite sides, are ears Zt, to which are pivoted downward-extending rods 7a', pivotally connected at their lower ends with bellcrank levers 7a2 7a2, secured between their ends to a rock-shaft 761, journaled in the cheeks A A2. The other arms of the bell-crank levers are pivotally connected to rods 7a2, which at their opposite ends are pivotally connected with the sides of the ram D. Thus in the reciprocation of the ram the reservoir I is swung up and down upon its hinge between the positions shown by full lines in Fig. 17 to the position indicated by the dotted lines in that figure. The base I of the reservoir I is corrugated, as indicated most clearly in Figs. 28 and 24, longitudinal slots 1l being provided between the corrugations. In the forward part of the reservoir is an inclined false bottom I2,which extends from the forward wall I3. The false bottom I2 has a corrugated and serrated edge il', which conforms to the corrugated base I and is slightly fluted at the ends z2 to permit a nail-head to pass beneath it when the shank of the nail extends through the respective slot t', as indicated in Fig. 17.

The openings afforded by the ends t2 will not permit a nail-head to pass through unless the shank thereof extends down through the respective slot t'. Extending between the cheeks at the forward edge of the reservoir I is a stationary cross-brace I1, and at the forward upward edges of the cheeks in the position shown is a cross bar or brace I5, L-shaped in cross-section, as shown in Fig. 19. Above the cross-bar I5 in the position shown is a cross-bar I0. Fastened against the under side of the bar I6 are a series of V-shaped deflectors I8, forming between them a series of nailreceiving slots t2. Extending from the deflectors to the bar I4 are a series of slats t1, having openings between them which register with the openings t in the base I of the nail-reservoir. Extending over the slats t1 is a plate 5 close enough to the slats to permit the heads to pass flatwise down the slats andv prevent the nails from jarring out.

I7 is a longitudinally-sliding bar resting `the rear face of the plate.

upon the L-shaped bar I5 and provided withl a series of vertical openings i0, cutting through Extending over the sides of the openings on the rear face of the plate are separating fingers or stops t7. (See, for example, Figs. 20, 2l, and 22.) In the bar I5 and registering with the slots t3 are openings 8, at the lower ends of which are short tubes t9. Fulcrumed at @'10 on the cheek A2 is a lever I0, connected at one end to the sliding bar I7. The lever is cam-shaped, as shown in Fig. 18, to afford the cam-surfaces @'11 @'12 at opposite sides of the fulcrum 1210. The bell-crank lever 7a2, as before mentioned, is upon the shaft k1, which passes through the cheek A2 and carries at its outer end an arm @'12, which slides along the cam-surfaces 11 'i12 of the lever I0. In the movement of the ram D in the forward direction-that is to say, in

the direction to the right in Fig. 2-the plate or bar I7 is moved to the position shown in Fig. 22, whereby the nails Y in the slots i3 will move by gravity against the surface of the plate or bar, as shown in Fig. 22. In the movement of the ram in the backward directionthat is to say, to the left in Fig. 2-the fingers or stops i7 pass between the first and second nail in each slot t2 and in the further movement of the bar direct the lirst nails into the openings t0 as the said openings register with the openings t2, whereby the nails drop into the tubular extensions Thus in the movement of the ram the reservoir I is agitated to distribute the nails in the guide-slots in the base I. The nails rest in the said slots, being prevented from passing downward in any other position by the false bottom I2. The nails pass from the openings 'L' to the openings between the slats and are positioned by the V-shaped detlectors I8 in the slot 2, and in each reciprocation of the plate or bar I7, brought about by the reciprocation of the ram, a nail is fed from each slot s to a tube extension t0.

Extending between the cheeks A' A2 is a crossebar A10, (see Figs. 6 and 27,) provided in its upper surface with a longitudinal T- slot h. On the cheek A2 in the position shown is an upright standard A11, (see Figs. 2 and 6,) firmly secured in place. On the top of this standard isa transverse bar A12, also rigid with the frame. On the bar A12 are upward extending brackets A13 A12, forming bearings for a horizontal shaft K. The bar A12 is provided with a longitudinal slot Zt.

(See Fig. 27.)

K is a vertical bar provided at its lower end with a bolt fitting the T-slot Zt and at its upper end with a bolt which passes through the slot Zt in the bar A12. By means of these bolts the upright bar K may be moved toward or away from the standard A11 and fastened in place to the bars A10 A12.

L L (see Fig. 6) are nailholders and guides. The guides L are provided with half-dovetailed flanges g, (see Fig. 30,) which engage half-dovetailed slots g' in the standard A11
